Omniscient Monks,

i meditate about minimizing keys and values in an hash tree.

data looks like this
[a, b, c] => [1, 2, 3]
[b, c]    => [2, 3, 4, 5]
[a, c, d] => [4, 5, 6, 7]
[d]       => [1, 2, 6]

basically i got an object containing two lists (e.g. key list and attribute list). now i need an algorithm which is able to reduce needed memory without loosing relations

the result should look like this:
[a, b, c, d] => [1, 2]
[a, b, c]    => [3]
[a, b, c, d] => [4, 5]
[a, c, d]    => [6, 7]

the problem is that the keys are really short (e.g. A1, A2,...) but the values (1,2,3,..) are really big data strings..
what would be your approach to do it efficient? i know that the simple way is to call the values by reference.. but thats not what i want!

kindly perlig
